Paper Mario: The Origami King has yet to be released officially, and it's already playable on PC through the Nintendo Switch emulators Yuzu and Ryujinx.

While both emulators seem to run the game just fine, Yuzu clearly has the upper edge thanks to more solid performance. Emulation, however, is set to get better in the near future, as the game, as already stated, has yet to release officially.
